Tongue is the strongest muscle in the body-Myth

As for the myth that the tongue is the strongest muscle in the body, this doesn't seem to be true by any definition of "strength." The masseter, or jaw muscle, is the strongest due its mechanical advantage, in which the muscles attach to the jaw to form a lever. The quadriceps and gluteus maximus have the highest concentration of striated muscle fibers, a pure measure of strength. The heart is the strongest muscle if you measure strength as continuous activity without fatigue.
